I am making my first bass and have no prior experience with a router. I have a good body design that I made myself and got some routing templates. I'm making practice/throw away guitars out of 4 pieces of 2x4 glued together. I've done two so far and have managed to ruin 3 routing templates (1 neck, 1 pickup, 1 control cavity). I'm using a Dewalt DWP611PK router and Whiteside bits (1/2" for neck, 3/4 for pickups, 1" for control cavity and edges). Any tips/advice would be greatly appreciated.
